AirPlay Improvements

AirPlay lets users stream audio and video from an iOS-based device to AirPlay–enabled devices such as televisions and audio systems. In iOS 5, developers can now use AirPlay to present application content on a nearby Apple TV 2. Users can now mirror the content of an iPad 2 to an Apple TV using AirPlay for any application. And developers who want to display different content (instead of mirroring) can assign a new window object to any UIScreen objects connected to an iPad 2 via AirPlay. In addition, you can now take advantage of AirPlay in the following ways: Applications that use AV Foundation can now use the AVPlayer class to stream audio and video content over AirPlay; see AV Foundation Framework Reference. The Media Player framework includes support for displaying “Now Playing” information in several locations, including as part of the content delivered over AirPlay; see MPNowPlayingInfoCenter Class Reference. The UIWebView class now supports the presentation of multimedia content over AirPlay. This support is enabled by default, but you can opt out of it if you want to.
